(a) Measles

Measles is not a waterborne disease; it is an airborne disease. It is a highly contagious viral infection that spreads through the air when an infected person coughs or sneezes. The virus is transmitted through respiratory droplets.

The other options are well-known waterborne diseases:

• Typhoid and Cholera are bacterial infections spread by consuming food or water contaminated with the feces of an infected person.
• Hepatitis (specifically Hepatitis A and E) is a viral infection that is also transmitted through the fecal-oral route, often via contaminated water.
